Sorry for the delayed update! It took us some time to decide what (if anything!) to do next.
Ultimately, we've decided to pursue a course of whole-lung radiation therapy. It is - as the name implies - radiation treatment to my entire lungs. Most commonly, this is done in pediatric tumors such as Ewing's sarcoma and Wilm's tumor. To be frank, there is no specific data to support the use of this treatment for my tumor. But, then again, as no one is entirely sure what my tumor is, that's not at all surprising! We spoke with radiation oncologists at several centers who agree that this is a reasonable treatment to pursue.
Because we're treating such a large area, the total radiation dose is quite low (I'll only receive twelve daily treatments - compared with thirty when my lymph nodes were treated last winter). Also, the amount of radiation received each day is slightly lower than normal. So, I should have few/no side effects during treatment. Most likely, I'll have no chronic side effects either (although there is a risk of reduced lung function).
We had some good imaging results this week. A CT scan on Friday showed that my lungs were remarkably clear. I have only one, 1 cm lung nodule (that's been stable for a few months). The rest of my lungs were clear (no nodules, 'infiltrates', etc.). While this doesn't rule out disease that we can't see (that's why we're pursuing more radiation...), it certainly is a very good result. In addition, no disease was visible elsewhere in my abdomen or pelvis. The CT did confirm that my spleen is - in fact - gone (it's nice to have an honest surgeon). Last of all, to exclude other systemic disease before I start lung radiation, I had a screening brain MRI that was termed 'unremarkable' (I tried not to take offense at this).
So, I'll start my radiation today, we'll finish in a couple of weeks, then we're off for vacation! As always, thank you for your prayers and support,
Robert and Gwyneth
